MACHINE FOR CUTTING FINGER-NOTCHES IN BOXES.

Application To all whom it may concern:

Be it known that l, Finn) It. HARRIS, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certstin new and useful improvements in M achinos for (hitting l ingor-Notches in Boxes, fully described and represented in the following specification and the accompanying drawings, forming it part of the some. v

'lhoob ect of this invention is to provide a machine for cutting linger h les or notches in the sides of boxes, of such construction that the boxes may be readily placed in position and removed from. the cutting or punching mechanism.

The invention has been made specially with the idea of providing the box making machine of my application for United States Letters Patent liled November 25th, 1903, lvo. 182,569, with means for cutting a finger notch in one of the sides of the boxes they are fed from the machine. Such machine is adapted for making boxes or box covers having a bottom section or top section, as the case may be, of polygonal form and especially of rectangular form and. having side sections extending from. the bottom or top. When such boxes are intended to be used for the cover portion of the box, it is desirable to out a linger notch in the edge of one of the box sides as the boxes are fed from the niaeliine, and the present invention is intended to provide mechanism for accomplishing this result, although the invention is adapted to be embodied in a complete independent anachine or combined with other nmchines from that shown in my said application. Although the part of the bin; tl'iat it is desirable to provide with such i'inger notches or holes, that is, the part having sides which extend outside of the other art of the box, is usually the box cover, sue 1 part will be termed a box herein, such term being used to include either the to or bottom or other por tion of a box whic r it is desired to provide with such finger notches or holes.

A full understanding of the invention can best be given from a detailed description of a preferred construction embodyinfg1 the varicscription will now be given in connection with the ac- Specification 0! Letters Patent.

coin )anviny drnwin 's shovvin such a. cont \J I) struciion applied to the machine of my said upplication No. 182,569.

In said drawingsz l igure 1 is a sectional elevation of the machine shown and described in my said application No. 182,569 provided with. mechsnism for punching linger notches in the sides of the boxes as they are fed from the machine. Fig. 2 is (a front View of the notch punching mechanism. Fig. 3 is a side View of the same, partly in section, and Fig. 'lfis a perspective view of the box after having the finger notches formed in one side thereof. 1

Referring first to Figs. 2 and 3, the mechanism shown in these figures comprises a feedway 1.0 through which the boxes are fed into and from position to be punched, a vertically reciprocating punch 11, and a die 12 for projecting into the box to co-aet with the punch. The punch 11 is carried by a cross head 13 mounted to slide vertically in suitable ways and rcciprocated by means of an eccentric pin 14 on the shaft 15 through a connecting rod 16 connected to the cross head. A clutch sleeve 17 splined to slide on the shaft 15 serves to connect the shaft with a sleeve 18 mounted to rotate freely on the shaft and driven. by means of a sprocket chain 1.) from a shaft 20, the sprocket wheel on. the shaft 20 and the sleeve 18 being of such relative size that the sleeve is given a number of revolutions for each rotation of the shaft 20. The sleeve 18 also preferably carries ally wheel 21 for giving momentum. The clutch 17 is operated to intermittently connect the shaft 15 with the sleeve 18 bv means of a lever 22, the movements of which are controlled by a cam 23 on the shaft 20, said can engaging a short arm carried by the shaft of the lever and acting to throw the lever against the pressure of a spring stud 24. A spring pressed annular friction late 25 is preferably provided, as shown in lg. 3, for,

caring against the end of the clutch. sleeve 17 for the purpose of stopping the rotation of the shaft on its being unclutched from the driving slee'v 18. The die 12is arranged to be retracted to permit the boxes to be moved edgewise through the feedwa. into punchin position. For this purpose t e die is earri y or formed by the end of a bar 26mounted to reciprocate horizontally and endwise in suitable hearings in the supporting frame. The bar is normally held under tension of a spring 27 in its retracted position, that is, moved to the right from the position shown in Fig. 3, with the die retracted out of the iath of the boxes and is intermittentlyproected for successive punching operations lnto the position shown in Fig. 3 by means of a crown cam 28 on the face of the cam disk 23.

In the operation of the machine, the boxes to be punched are fed edgewise through the feedway 10 into position while the die 12 is retracted. The die will then be projected into position to cooperate with the punch 11 and the shaft 1.5 having been clutched to the sleeve 18 the punch will operate to cut a. finger notch in the side of the box. The shaft will then be disconnected from the sleeve 18 and the die will be retracted to permit the box to be moved onward through the feedway 10 and another box to be moved into position to be unched.

The boxes may e fed through the feedway 10 by hand or by any suitable mechanism for feeding the boxes .into osition in time for the operations of the pane ing mechanism. Such a construction is shown in F ig. 1 where the punchin mechanism is shown as combined with the box making and covering machine of my application No. 182,569 above referred to. In said machine the formed boxes are fed edgewise from the box forming and. covering devices by means of pushing lingers 265 carried by a horizontally reciprocating gripper slide 116. The notch punching, mechanism is so positioned on said machinc that as the completed boxes are moved edgcwise from the box forming and coverin devices by the pushing lingers 265 they w 1 be fed into the feedway 10 and to position with the central portion of the up )cr side of the box beneath the punch 11. "he die 12 will then be projected into operative position and the punch operated while the slide 11 is making its next reciproeation. The die will then be retracted while the punch remains in its elevated position as the slide 116 moves to the right again, as shown in Fig. 1 and the pusher 265 carries another colll pleted box from the forming and covering devices to the punching mechanism, the box previously punched being ejected from the punching mechanism by the next box moved into position to he punched.

As shown in Fig. l the punching mechanism is driven from the shaft 35 of the box forming machine by means of a sprocket chain running on sprocket wheels on the shaft 35 and the shaft 21), said wheels being timed to cause an operation of the punching machine for each rotation of the shaft 35, that is, for each box formed and in time with the movements of the slide 116.

As the other parts of the box forming and covering machine shown in Fig. 1 are not concerned particularly with the present invention and are shown only for the purpose of illustrating the application of the punching mechanism to such machine, further description thereof is not necessary in this application.

It will be understood that the invention is not to be limited to the exact construction and arrangement of parts shown but that the invention includes various changes and modifications thereof within the terms of the claims.

What is claimed isz- 1. The combination with a punch and a die for cutting finger notches in the sides of boxes, of means for reciprocating the member which extends inside the box in a direction transverse to the direction of cutting movement of the punch or die and transverse to the direction of movement of the boxes into and out of position to be punched to permit the box to be moved into and out of position to be punched, substantially as described.

2. The combination with a punch for cutting fin er notches in the sides of boxes, and means or reciprocating the punch, of a die which extends into the box when in operative position, a feedway through which the boxes move edgewisc of the bottom of the box, and means for retracting the die in a direction transverse to the direction. of movement of'the punch and of the boxes to permit the boxes to move through the fcedway, substantially as described.

3. The combination with a punch for cutting linger notches in the sides of boxes, and means for reciprocating the punch, of a die which extends into the box when in operative position, a l'ccdway, means for advancing boxes successively through the iccdway cdgcwise of the bottom of the box into position to he punched, and means for retracting the die in a direction transverse to the direction of movement of the punch and of the boxes to permit the boxes to be moved into position to he punched, substantially as described.

4. The combination with a punch for cutting linger notches in the sides of boxes, and means for ria-iprocating the punch, of a die which extends into the box when in operative position, a i'ecdway through which the boxes movc cdgcwisc of the bottom oi the. box, means for retracting the die in a direction transverse to the direction of moventent .of the punch and of the boxes to pcrmitdlni boxes to move through the 'l'cedway, punch operating means, and means for interrupting the operation of the punch operating means when the d ie is retracted, substantially as described.
